The evolution of our patented Frameless Design continues with the X1S, same epic features as the X1 - but in a smaller portion size. Premium Injected Spherical lenses offer an expansive field of view, while our LUMALENS Technology allows for unmatched clarity and contrast. Triple-layer face foam, 100% UV protection, armoured venting, and a 200% stronger Super Anti-Fog Coating are cherries on top.
